TUCSON — Huston Street’s path to the opening day roster became clearer today. He threw live BP — 20 pitches — and is on track to pitch in a game late next week. Rafael Betancourt also threw a bullpen session, but pitching coach Bob Apodaca acknowledged that he’s two weeks behind Street. That means he won’t pitch in a game next week and is racing against the clock to be ready April 5.

I wouldn’t be shocked if he starts the year on the DL, it’s back-dated, and he comes off that first weekend. Matt Belisle (forearm stiffness) is also moving forward and will pitch Sunday.
